TE Connectivity 3-1761603-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-1761603-7 is an active rectangular connector header designed for through-hole mounting applications. This shrouded 64-position connector operates at 0.100" (2.54mm) pitch and supports board-to-cable/wire interconnections with push-pull fastening. The connector features gold-plated mating contacts and tin-plated posts, rated for 1A per contact at 250VAC across an operating temperature range of -65°C to 105°C. Substitute parts are identified when equivalent electrical and mechanical specifications are required and the primary part becomes unavailable or when alternative packaging or compliance certifications are necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-1761603-7 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Equivalence Criteria:

• 64-position connector with 2-row configuration
• 0.100" (2.54mm) mating pitch and row spacing
• Male pin contact type with phosphor bronze material
• Gold-plated mating contacts and tin-plated posts
• Push-pull fastening mechanism
• Shrouded 4-wall design with keying slot
• Through-hole solder termination
• UL94 V-0 flammability rating
• MSL 1 (Unlimited) moisture sensitivity

Mechanical Compatibility:

• Board-to-cable/wire connection style
• Square contact shape
• Solder termination method

The substitute parts Amphenol ICC (FCI) 75869-110LF and 75869-310LF meet these core electrical and mechanical requirements. Variations in contact length dimensions, insulation material composition (thermoplastic glass-filled versus PBT), and contact finish thickness do not prevent functional substitution when the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity 3-1761603-7 is the specified component and remains the first choice when available. This part carries ROHS3 compliance certification and is actively manufactured with documented inventory availability.

Substitute Part Selection - Amphenol ICC 75869-110LF: The 75869-110LF qualifies as a direct substitute when the primary part is unavailable. This part maintains electrical and mechanical equivalence across all critical parameters including connector type, position count, pitch, fastening mechanism, and flammability rating. The part carries RoHS compliance and REACH affected status. Contact finish thickness on mating surfaces matches the primary part at 30.0µin (0.76µm). Insulation material differs (thermoplastic glass-filled versus PBT) but does not affect functional compatibility. Packaging is supplied in tube format rather than bulk.

Substitute Part Selection - Amphenol ICC 75869-310LF: The 75869-310LF provides an alternative substitute with identical mechanical and electrical characteristics to the 75869-110LF. This part differs only in mating contact finish thickness at 15.0µin (0.38µm), which is reduced compared to both the primary part and the 75869-110LF. All other parameters remain equivalent. This part carries RoHS compliance and REACH affected status. Packaging is supplied in tube format.

Compliance Considerations: All three parts meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) ratings. The primary part carries ROHS3 certification while substitute parts carry standard RoHS compliance. Both substitute parts are REACH affected. Selection between substitute parts depends on contact finish thickness requirements and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 75869-110LF be used as a direct replacement for the TE Connectivity 3-1761603-7?

A: Yes. The 75869-110LF meets all critical electrical and mechanical specifications including 64-position configuration, 0.100" (2.54mm) pitch, male pin contacts, phosphor bronze material, gold-plated mating surfaces, tin-plated posts, push-pull fastening, shrouded 4-wall design, through-hole solder termination, and UL94 V-0 flammability rating. Functional compatibility is established across these parameters.

Q: What is the difference between the 75869-110LF and 75869-310LF?

A: Both parts are functionally equivalent. The primary difference is mating contact finish thickness: the 75869-110LF provides 30.0µin (0.76µm) matching the primary part, while the 75869-310LF provides 15.0µin (0.38µm). Post contact finish thickness is identical at 78.7µin (2.00µm) for both Amphenol parts. Selection depends on specific contact durability requirements.

Q: Does the insulation material difference affect substitution?

A: No. The primary part uses polybutylene terephthalate (PBT) while the Amphenol substitutes use thermoplastic glass-filled material. Both materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation properties for this application. Material selection does not prevent functional substitution.

Q: Are there packaging differences between these parts?

A: Yes. The TE Connectivity 3-1761603-7 is supplied in bulk packaging, while both Amphenol ICC substitutes (75869-110LF and 75869-310LF) are supplied in tube packaging. Packaging format does not affect connector functionality but may impact inventory management and handling procedures.

Q: Do all three parts meet RoHS compliance?

A: Yes. The primary part carries ROHS3 compliance certification. Both Amphenol substitutes carry RoHS compliance certification. All three parts are suitable for RoHS-regulated applications. The Amphenol parts carry REACH affected status while the primary part shows vendor undefined REACH status.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the design accommodates the mechanical dimensions. Contact length specifications vary slightly: the primary part provides 0.240" (6.10mm) mating contact length and 0.102" (2.60mm) post length, while Amphenol substitutes provide 0.236" (6.00mm) mating contact length and 0.120" (3.05mm) post length. Insulation height also differs: primary part at 0.350" (8.89mm) versus Amphenol parts at 0.377" (9.57mm). These dimensional variations require verification against PCB layout and mating connector specifications.

Q: What is the current and voltage rating for the substitute parts?

A: The primary part is rated for 1A per contact at 250VAC. Current and voltage ratings are not specified in the available data for the Amphenol substitutes. When current and voltage specifications are critical to the application, the primary TE Connectivity part with documented ratings should be prioritized.

Q: Are all parts suitable for the same operating temperature range?

A: The primary part operates across -65°C to 105°C. Operating temperature specifications are not provided for the Amphenol substitutes in the available data. When operating temperature range is a design requirement, the primary part with documented specifications should be selected.
