Molex 0940304071 Quick Connect Crimp Terminal - Equivalent & Substitute Parts

Part Overview

The Molex 0940304071 is a 0.250" (6.35mm) Quick Connect Male crimp terminal designed for 18-20 AWG wire applications. This non-insulated brass terminal with tin finish is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and design continuity. Substitute parts must maintain identical mechanical dimensions, electrical performance characteristics, and crimp termination compatibility to ensure proper connector assembly and reliable circuit connections.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0940304071 is determined by strict equivalence across the following critical parameters: tab width (0.250"), tab thickness (0.032"), termination method (crimp), gender (male), contact material (brass), and insulation diameter range compatibility. Wire gauge compatibility extends to parts rated for 18-20 AWG or broader ranges that encompass 18-20 AWG operation. Parts meeting these criteria maintain mechanical interchangeability and electrical performance within the original application envelope.

The identified substitute parts are classified as follows:

Direct Equivalent (880688-1): Maintains all critical mechanical and electrical parameters within specification tolerance.

Extended Range Equivalent (62553-3): Expands wire gauge capability to 18-22 AWG while preserving all other critical parameters, providing broader application flexibility.

Engineering Selection Recommendations

TE Connectivity 880688-1 is the direct functional equivalent for applications requiring exact specification compliance with the original Molex 0940304071. This part maintains identical mechanical dimensions and wire gauge range, ensuring seamless integration into existing designs. Active product status and ROHS3 compliance support long-term procurement availability.

TE Connectivity 62553-3 provides an extended-range alternative suitable for applications where wire gauge flexibility to 22 AWG is acceptable. The manufacturer-recommended designation reflects engineering validation for this substitution path. Insulation diameter range is slightly narrower (0.085" ~ 0.125" versus 0.079" ~ 0.130"), requiring verification that target wire insulation falls within this specification. Active product status and RoHS compliance ensure supply chain continuity.

Both substitute parts are manufactured by TE Connectivity AMP Connectors, a primary supplier in the 0.250" Quick Connect terminal category, and carry equivalent regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 880688-1 be used as a direct replacement for Molex 0940304071?

A: Yes. The 880688-1 maintains identical tab width (0.250"), tab thickness (0.032"), wire gauge range (18-20 AWG), termination method (crimp), and contact material (brass). Mechanical interchangeability is confirmed across all critical parameters.

Q: What is the difference between 880688-1 and 62553-3?

A: The primary difference is wire gauge range. The 880688-1 matches the original 18-20 AWG specification, while the 62553-3 extends to 18-22 AWG. The 62553-3 also has a slightly narrower insulation diameter range (0.085" ~ 0.125" versus 0.079" ~ 0.130"). Tab length differs marginally (0.620" versus 0.618"), within typical manufacturing tolerance.

Q: Are both substitute parts RoHS compliant?

A: Yes. The 880688-1 carries ROHS3 compliance, and the 62553-3 carries RoHS compliance. Both meet regulatory requirements for restricted substance elimination.

Q: What packaging formats are available for the substitute parts?

A: Both TE Connectivity substitute parts are supplied in Cut Tape (CT) packaging format.

Q: Does the insulation diameter range difference in 62553-3 affect compatibility?

A: The 62553-3 insulation diameter range (0.085" ~ 0.125") is narrower than the original (0.079" ~ 0.130"). Verify that wire insulation dimensions in your application fall within the 62553-3 range before selection. If wire insulation is below 0.085" or above 0.125", the 880688-1 is the appropriate choice.

Q: What is the MSL rating for these terminals?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
