TE Connectivity AMP Connectors 61668-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 61668-1 is an edge terminal connector with bifurcated leaf design, classified as a Card Edge Connector. This non-gendered terminal accommodates wire gauges from 18 to 24 AWG and utilizes crimp termination with tin-lead contact finish on brass material. The part is currently in active product status with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, packaging format preferences, or compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 61668-1 is determined by the following critical parameters that must remain constant across all equivalent parts:

Mandatory Matching Parameters:

• Manufacturer: TE Connectivity AMP Connectors
• Category: Card Edge Connectors
• Series: Bifurcated Leaf
• Pin or Socket Configuration: Non-Gendered
• Wire Gauge: 18-24 AWG
• Contact Termination: Crimp
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active
• ECCN: EAR99
• HTSUS Code: 8536.90.4000

Parameters Permitted to Vary:

• Packaging format (Tape & Reel versus Cut Tape)
• Contact Material (Brass versus Phosphor Bronze)
• Contact Finish composition (Tin-Lead versus Tin)
• RoHS compliance status
• REACH compliance status

The identified substitutes 3-61668-1 and 61668-2 maintain all mandatory parameters while differing in packaging, contact material, and finish specifications. These variations do not affect the functional compatibility of the terminal in card edge connector applications.

Parameter Comparison

Engineering Selection Recommendations

61668-1 (Main Part): Select this part when Tape & Reel packaging is required for automated assembly processes. This configuration is suitable for applications where REACH Affected status is acceptable. The tin-lead contact finish on brass material provides the specified electrical and mechanical characteristics for the bifurcated leaf terminal design.

3-61668-1 (Substitute): This substitute is functionally equivalent to the main part with identical contact material (brass) and wire gauge specifications. The primary differences are Cut Tape packaging format and ROHS3 compliance status. This part is suitable for applications requiring RoHS3 compliance and REACH Unaffected status. The tin contact finish replaces the tin-lead composition of the main part. Significantly higher inventory availability (95,581 pieces) supports extended production runs.

61668-2 (Substitute): This substitute maintains the same wire gauge, termination method, and MSL rating as the main part. The contact material differs (phosphor bronze instead of brass) while retaining tin finish. This part achieves ROHS3 compliance and is suitable for applications where phosphor bronze contact material is acceptable. Cut Tape packaging is provided. REACH status is vendor-defined and requires clarification for specific regulatory applications.

Selection between substitutes depends on packaging requirements, compliance mandates, and contact material specifications for the intended application.

Frequently Asked Questions (FAQ)

Q: Can 3-61668-1 be used as a direct replacement for 61668-1 in production assembly?

A: Yes. Both parts maintain identical wire gauge (18-24 AWG), contact termination (crimp), series (bifurcated leaf), and configuration (non-gendered). The primary difference is packaging format: 61668-1 is supplied in Tape & Reel while 3-61668-1 is supplied in Cut Tape. Contact finish differs (tin-lead versus tin), and 3-61668-1 is ROHS3 compliant. Compatibility depends on whether the application accepts these variations.

Q: What is the difference between the contact finishes in these parts?

A: The 61668-1 features tin-lead contact finish on brass material. Both substitutes (3-61668-1 and 61668-2) feature tin contact finish. The 61668-2 additionally uses phosphor bronze as the contact material instead of brass. These material and finish variations affect corrosion resistance and electrical properties but do not change the fundamental crimp termination compatibility with 18-24 AWG wire.

Q: Which substitute should be selected for RoHS-compliant applications?

A: Both 3-61668-1 and 61668-2 are ROHS3 compliant. The main part 61668-1 has RoHS status listed as "Not applicable." For applications with mandatory RoHS compliance requirements, either substitute is acceptable based on other selection criteria such as contact material preference and packaging format.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats do not affect the electrical or mechanical performance of the terminal itself. Packaging selection is determined by assembly process requirements: Tape & Reel is used for automated pick-and-place equipment, while Cut Tape is used for manual or semi-automated assembly processes.

Q: What is the significance of REACH status differences between these parts?

A: The main part 61668-1 is listed as REACH Affected, indicating it contains substances of concern under REACH regulations. The substitute 3-61668-1 is REACH Unaffected, meaning it does not contain such substances. The substitute 61668-2 has Vendor Undefined REACH status. For applications subject to REACH compliance, 3-61668-1 is the appropriate selection.

Q: Can 61668-2 be used interchangeably with 61668-1 despite the phosphor bronze contact material?

A: Both parts are functionally equivalent within the bifurcated leaf terminal series and accept 18-24 AWG crimp termination. The phosphor bronze contact material in 61668-2 differs from the brass material in 61668-1. Interchangeability depends on whether the application specifications permit phosphor bronze contact material. Contact material selection affects mechanical strength and corrosion resistance characteristics.

Q: What inventory considerations apply to these substitutes?

A: The main part 61668-1 has 643 pieces in stock. The substitute 3-61668-1 has significantly higher availability at 95,581 pieces, supporting extended production requirements. The substitute 61668-2 has 5,189 pieces available. Inventory levels may influence part selection for high-volume applications.
