Substitute Part Grouping Explanation

Substitution of the obsolete 104128-7 with active equivalent part 1-1761606-3 is based on strict alignment of critical electrical and mechanical parameters. Both connectors maintain identical specifications for connector type (Header), contact type (Male Pin), position count (40), row configuration (2 rows), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting method (Through Hole), shrouding style (Shrouded - 4 Wall), fastening mechanism (Latch Lock/Eject Hooks, Long), voltage rating (250VAC), current rating (1A per Contact), operating temperature range (-65°C ~ 105°C), and flammability rating (UL94 V-0).

Minor variations exist in contact dimensions, insulation material composition, and contact finish material specifications. These variations remain within acceptable tolerances for functional interchangeability in standard board-to-cable/wire applications. The substitute part 1-1761606-3 carries active product status and RoHS3 compliance, addressing regulatory requirements not met by the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1761606-3 serves as the direct functional equivalent for the obsolete 104128-7. Selection of the substitute part is supported by the following engineering criteria:

Product Status and Availability: The 1-1761606-3 maintains active product status with confirmed inventory availability (1523 pieces in stock), whereas the 104128-7 is classified as obsolete. This transition ensures long-term supply chain continuity and component availability for production and field replacement applications.

Regulatory Compliance: The substitute part 1-1761606-3 carries RoHS3 compliance certification, addressing current regulatory requirements for electronic components in most jurisdictions. The original part 104128-7 is RoHS non-compliant, creating potential restrictions for new designs and applications subject to RoHS directives.

Electrical and Mechanical Compatibility: Both parts maintain identical electrical ratings (250VAC, 1A per Contact), operating temperature range (-65°C ~ 105°C), and mechanical specifications (40 positions, 2 rows, 0.100" pitch, Through Hole mounting, Shrouded - 4 Wall, Latch Lock/Eject Hooks). These parameters ensure direct functional interchangeability in existing circuit board designs and cable assemblies.

Contact Material and Finish Specifications: The substitute part employs Phosphor Bronze contact material with Tin finish on posts, compared to Brass with Tin-Lead finish on the original part. Both material systems maintain equivalent electrical conductivity and contact reliability within the specified current and voltage ratings. The elimination of lead in the substitute part aligns with RoHS3 requirements.

Insulation Material: The substitute part utilizes Polybutylene Terephthalate (PBT) insulation material in place of the original Polyamide (PA) with glass filling. Both materials achieve UL94 V-0 flammability rating and maintain equivalent performance across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 1-1761606-3 be used as a direct replacement for the 104128-7 in existing designs?

A: Yes. Both connectors maintain identical electrical ratings (250VAC, 1A per Contact), mechanical configuration (40 positions, 2 rows, 0.100" pitch), mounting type (Through Hole), and shrouding style (Shrouded - 4 Wall). The connectors are functionally interchangeable in board-to-cable/wire applications without circuit design modifications.

Q: What are the dimensional differences between these two parts?

A: Contact length specifications differ slightly. The 104128-7 features a mating contact length of 0.240" (6.10mm) and post length of 0.120" (3.05mm), while the 1-1761606-3 provides mating contact length of 0.237" (6.02mm) and post length of 0.102" (2.60mm). Insulation height also varies: 0.385" (9.78mm) for the original part versus 0.404" (10.26mm) for the substitute. These dimensional variations remain within acceptable tolerances for standard connector applications.

Q: Why does the substitute part have different contact material and finish specifications?

A: The 1-1761606-3 employs Phosphor Bronze with Tin finish to achieve RoHS3 compliance by eliminating lead content. The original 104128-7 uses Brass with Tin-Lead finish. Both material systems provide equivalent electrical conductivity and contact reliability within the specified current and voltage ratings. The material change reflects modern manufacturing standards and regulatory requirements.

Q: Is the 1-1761606-3 available in the same packaging as the 104128-7?

A: The substitute part 1-1761606-3 is supplied in Tube packaging. Original packaging information for the 104128-7 is not specified in the available documentation. Packaging format does not affect connector functionality or interchangeability in applications.

Q: What is the inventory status for the substitute part?

A: The 1-1761606-3 has 1523 pieces in stock as new original inventory. The obsolete 104128-7 has 688 pieces remaining in stock. The substitute part provides superior long-term availability due to its active product status.

Q: Are there any temperature or voltage limitations when using the 1-1761606-3 as a replacement?

A: No. Both connectors maintain identical operating temperature range (-65°C ~ 105°C) and voltage rating (250VAC). The substitute part operates within the same electrical and thermal specifications as the original part.

Q: Does the insulation material change affect connector performance?

A: No. Both the original Polyamide (PA) with glass filling and the substitute Polybutylene Terephthalate (PBT) achieve UL94 V-0 flammability rating and maintain equivalent electrical insulation properties across the operating temperature range. The material change reflects modern manufacturing practices while preserving performance characteristics.
