Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 170-202-170L002 is determined by the following critical parameters:

Primary Matching Criteria:

• Contact type: Female socket
• Contact termination: Crimp
• Wire gauge compatibility: 20-26 AWG (or overlapping range)
• Contact finish: Gold preferred for corrosion resistance and signal integrity

Secondary Considerations:

• Contact form: Machined contacts provide consistent performance
• Product status: Active status ensures ongoing availability
• Regulatory compliance: ROHS3 and REACH status alignment

The substitute parts identified fall into two categories: direct functional equivalents within the same connector family, and cross-category alternatives that meet the electrical and mechanical requirements despite different connector form factors.

Parameter Comparison

Engineering Selection Recommendations

170-202-170L003 (NorComp Inc.)

This is the primary recommended substitute. It maintains identical electrical and mechanical specifications within the same D-Sub connector family and series. Both parts share ROHS3 compliance and REACH unaffected status. The 170-202-170L003 is currently in active production with substantial inventory availability (12,785 pcs), ensuring long-term supply chain stability. This part requires no design modification and provides direct form-factor compatibility.

794139-3 (TE Connectivity AMP-DUAC)

This part meets wire gauge and contact finish requirements (22-26 AWG, gold finish) but operates within a different connector category (rectangular vs. D-Sub). Substitution requires mechanical redesign of the connector assembly. The part carries RoHS non-compliance status and undefined REACH compliance, which may conflict with regulatory requirements in certain applications. Use only when form-factor change is acceptable and regulatory constraints permit.

0457503112 (Molex Mini-Fit Plus HCS)

This rectangular connector socket operates at 16 AWG, which falls below the specified 20-26 AWG range of the main part. The tin finish differs from the gold specification. Substitution requires mechanical redesign and may introduce signal integrity concerns in applications sensitive to contact resistance. This option is viable only when wire gauge reduction and finish change are functionally acceptable.

SVT-41T-P1.1 (JST VT Series)

This rectangular connector socket supports 16-20 AWG wire gauge, which partially overlaps the main part specification but does not cover the full 20-26 AWG range. The tin finish differs from gold. Substitution requires mechanical redesign and limits applicability to lower wire gauge applications. Use only when form-factor change and wire gauge limitation are acceptable.

Frequently Asked Questions (FAQ)

Q: Can 170-202-170L003 be used as a direct replacement for 170-202-170L002?

A: Yes. Both parts are D-Sub female socket contacts with identical wire gauge (20-26 AWG), crimp termination, gold finish, and machined contact form. The 170-202-170L003 is the active production equivalent and requires no design changes.

Q: What are the wire gauge limitations when considering cross-category substitutes?

A: The main part specifies 20-26 AWG. The Molex 0457503112 is rated for 16 AWG only, which is narrower than the specified range. The JST SVT-41T-P1.1 covers 16-20 AWG, leaving the upper 20-26 AWG range partially unsupported. These parts are suitable only for applications operating within their respective wire gauge ranges.

Q: Does contact finish affect substitution decisions?

A: Contact finish impacts signal integrity and corrosion resistance. The main part specifies gold finish. Tin-finished alternatives (Molex 0457503112, JST SVT-41T-P1.1) provide lower contact resistance but reduced corrosion protection. Gold-finished alternatives (TE 794139-3, NorComp 170-202-170L003) maintain the original performance characteristics.

Q: Are there regulatory compliance concerns with substitute parts?

A: The TE Connectivity 794139-3 is RoHS non-compliant and has undefined REACH status, which may violate regulatory requirements in certain markets. The NorComp 170-202-170L003 maintains ROHS3 compliance and REACH unaffected status, matching the original part. Verify regulatory requirements before selecting alternatives.

Q: What packaging considerations apply to these substitutes?

A: The main part packaging is not specified. The 170-202-170L003 is supplied in bulk packaging. The Molex 0457503112 is supplied in bulk. The TE 794139-3 packaging is not specified. The JST SVT-41T-P1.1 is supplied in tape and reel format. Confirm packaging compatibility with assembly processes.

Q: Can rectangular connector substitutes be used in D-Sub applications?

A: No. Rectangular connectors (Molex, TE, JST) have different mechanical form factors and cannot physically interface with D-Sub connector housings. Substitution requires complete redesign of the connector assembly and mating interface. Use rectangular alternatives only when mechanical redesign is feasible and acceptable.
