Substitute Part Grouping Explanation

Substitution of the obsolete 735239-6 is based on strict alignment of the following critical parameters:

Primary Compatibility Criteria:

Tab width of 0.250" (6.35mm) for mechanical mating compatibility
Female gender for connector interface matching
Crimp termination method for assembly process compatibility
Non-insulated design for electrical and mechanical form factor equivalence
Brass contact material with tin finish for electrical performance and corrosion resistance
Free-hanging in-line mounting configuration
Overall length of 0.713" (18.10mm) for spatial fit requirements
Faston series classification for standardized quick-connect applications

The substitute part 735273-2 satisfies all primary compatibility criteria while offering the additional specification of defined wire gauge range (14-18 AWG) and maintains active product status with current manufacturing availability.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 735273-2 serves as the direct functional equivalent for the obsolete 735239-6 based on the following engineering criteria:

Mechanical Compatibility: Both parts maintain identical tab width (0.250"), overall length (0.713"), and mounting configuration, ensuring direct form-factor substitution in existing connector interfaces.

Electrical Compatibility: Identical contact material (brass) and finish (tin) provide equivalent electrical performance and corrosion resistance characteristics.

Regulatory Compliance: Both parts meet RoHS compliance requirements and carry MSL rating of 1 (Unlimited), satisfying environmental and moisture sensitivity specifications for industrial applications.

Product Availability: The 735273-2 maintains active product status with documented inventory availability (898 pcs), whereas the 735239-6 is obsolete. Selection of the substitute part ensures access to current manufacturing and supply chain continuity.

Wire Gauge Definition: The 735273-2 specifies 14-18 AWG wire gauge compatibility, providing explicit termination guidance absent in the original part specification. This addition enhances assembly process control without restricting application scope.

Frequently Asked Questions (FAQ)

Q: Can the 735273-2 be used as a direct replacement for the 735239-6 in existing assemblies?

A: Yes. Both parts share identical mechanical dimensions (tab width 0.250", overall length 0.713"), identical contact materials and finishes, and identical mounting configuration. The 735273-2 is mechanically and electrically compatible for direct substitution in applications previously using the 735239-6.

Q: What is the significance of the wire gauge specification in the 735273-2?

A: The 735273-2 specifies 14-18 AWG wire gauge compatibility, whereas the 735239-6 does not provide this specification. This defined range in the substitute part ensures proper crimp termination for wires within this gauge specification. Applications using wire gauges outside this range require evaluation against the insulation diameter range (0.122" ~ 0.169").

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant and carry identical MSL ratings (1 - Unlimited). No compliance disadvantages exist in selecting the 735273-2 as a substitute.

Q: Why is the insulation diameter range slightly different between the two parts?

A: The 735239-6 specifies 0.118" ~ 0.169" while the 735273-2 specifies 0.122" ~ 0.169". The substitute part's range is a subset of the original specification, representing a refined manufacturing tolerance. This difference does not restrict compatibility for standard wire insulation diameters within the 0.122" ~ 0.169" range.

Q: What is the inventory status for these parts?

A: The 735239-6 is obsolete with 1085 pcs documented as new original stock. The 735273-2 is an active product with 898 pcs currently in stock, providing ongoing supply availability for new production and maintenance requirements.

Q: Are both parts suitable for the same mounting applications?

A: Yes. Both parts are configured for free-hanging in-line mounting with identical overall dimensions and contact configurations, making them suitable for identical mounting applications.
