TE Connectivity 55675-1 Quick Connect Female Crimp Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 55675-1 is a 0.250" (6.35mm) Quick Connect Female Crimp Connector designed for 18-22 AWG wire applications. This terminal features non-mating end insulation and is part of the Faston and PIDG series connector family. The component is classified as an Active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to address packaging format variations and inventory availability while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 55675-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 55675-2 maintains identical specifications in the following critical areas:

Electrical Parameters: Wire gauge range (18-22 AWG), contact material (Brass), contact finish (Tin), and insulation type (Non-Mating End Insulated)

Mechanical Parameters: Tab width (0.250"), tab thickness (0.032"), tab length (0.305"), overall length (0.900"), and insulation diameter (0.135")

Compliance & Environmental: ROHS3 compliance, MSL 1 rating, and identical ECCN/HTSUS classifications

The only difference between the main part and substitute is the packaging format: the 55675-1 is supplied in Bulk packaging, while the 55675-2 is supplied in Cut Tape (CT) packaging. This distinction affects procurement and assembly processes but does not alter component functionality or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the 55675-1 and 55675-2 are Active products with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by packaging requirements and inventory availability rather than functional performance.

55675-1 (Bulk Packaging): Suitable for high-volume manufacturing operations and applications requiring loose component handling. Current inventory: 890 pieces.

55675-2 (Cut Tape Packaging): Suitable for automated assembly processes and applications requiring tape-and-reel or cut tape format. Current inventory: 2262 pieces.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, ensuring equivalent regulatory and trade compliance. The MSL 1 rating indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can 55675-2 be used as a direct replacement for 55675-1?

A: Yes. The 55675-2 is electrically and mechanically identical to the 55675-1. The only difference is packaging format (Cut Tape versus Bulk). Both parts are functionally equivalent for all circuit and assembly applications.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components in a container, suitable for manual assembly and high-volume pick-and-place operations. Cut Tape packaging supplies components on adhesive tape in specified quantities, optimized for automated assembly equipment. The components themselves are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both 55675-1 and 55675-2 are ROHS3 compliant. They meet all applicable environmental and hazardous substance restrictions.

Q: What wire gauges are compatible with these connectors?

A: Both parts are rated for 18-22 AWG wire. This range must be strictly observed during crimping and assembly to ensure proper contact pressure and electrical performance.

Q: What is the MSL rating and why does it matter?

A: Both parts carry an MSL 1 rating, indicating unlimited moisture sensitivity. This means the components have no moisture absorption limitations and do not require special storage or handling conditions prior to assembly.

Q: Can these connectors be used interchangeably with other Faston series terminals?

A: Substitution is limited to parts with identical tab width (0.250"), tab thickness (0.032"), and wire gauge specifications. The 0.250" tab width is specific to this connector family and is not interchangeable with other Faston tab widths.

Q: What is the contact material and finish?

A: Both parts feature Brass contacts with Tin finish. This combination provides reliable electrical conductivity and corrosion resistance for general-purpose quick-connect applications.
