Molex 0705510071 Equivalent & Substitute Parts

Part Overview

The Molex 0705510071 is an active rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded 2-position header with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection requirements across automotive, industrial, medical, and general purpose applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents.

Engineering Selection Recommendations

Both the Molex 0705510071 and TE Connectivity 103904-1 are active products with established compliance certifications. Selection between these parts is based on availability, packaging requirements, and compliance status:

Molex 0705510071: ROHS3 compliant, REACH unaffected status. Suitable for applications requiring strict RoHS3 certification. Packaged in bulk format.

TE Connectivity 103904-1: REACH affected status, RoHS status not applicable. Packaged in tube format. Provides extended operating temperature range (-65°C minimum versus -40°C). Includes keying slot feature not present in primary part.

Both parts maintain identical electrical performance at rated voltage (250V for Molex; voltage rating not specified for TE Connectivity) and support the same connector interface geometry. Contact material and insulation material differences do not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 103904-1 be used as a direct replacement for Molex 0705510071?

A: Yes. Both parts share identical pitch (0.100"), position count (2), row configuration (1), mounting type (through-hole right-angle), shrouding (4-wall), and contact geometry (square male pins with gold mating finish). Mechanical and electrical compatibility is established.

Q: What are the dimensional differences between these parts?

A: Contact length mating differs by 0.010" (0.26mm), with TE Connectivity at 0.230" versus Molex at 0.240". Insulation height differs by 0.015" (0.38mm), with TE Connectivity at 0.200" versus Molex at 0.215". These variations remain within standard connector tolerance ranges and do not affect mating performance.

Q: Does the keying slot feature on TE Connectivity 103904-1 affect compatibility?

A: The keying slot is an additional feature that does not interfere with standard mating. It provides polarization capability without requiring modification to existing designs.

Q: What is the significance of the contact material difference (Phosphor Bronze versus Brass)?

A: Both materials provide adequate electrical conductivity and mechanical durability for this connector class. Material selection does not affect electrical performance in standard applications.

Q: How do packaging formats differ between these parts?

A: Molex 0705510071 is supplied in bulk packaging. TE Connectivity 103904-1 is supplied in tube packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are there compliance differences between these parts?

A: Molex 0705510071 carries ROHS3 compliance and REACH unaffected status. TE Connectivity 103904-1 is REACH affected with RoHS status not applicable. Compliance requirements for the end application determine which part is appropriate.
