Engineering Selection Recommendations
The TE Connectivity 205202-7 is the direct equivalent substitute for the obsolete 5-66506-3. Selection of the 205202-7 is supported by the following engineering factors:
Compliance and Certification: Both parts maintain RoHS compliance and identical MSL ratings, ensuring compatibility with current environmental and regulatory requirements.
Product Status: The 205202-7 holds active product status with confirmed manufacturing availability (1329 pcs in stock), whereas the 5-66506-3 is obsolete. This transition eliminates supply chain risk for ongoing production and field service requirements.
Functional Equivalence: All critical electrical and mechanical parameters are identical, including wire gauge range, contact material, finish specification, and termination method. The parts are directly interchangeable within AMPLIMITE HDP-20 connector assemblies.
Packaging Consideration: The 205202-7 is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures compared to the original packaging specification.
Frequently Asked Questions (FAQ)
Q: Can the 205202-7 be used as a direct replacement for the 5-66506-3 in existing designs?
A: Yes. The 205202-7 is functionally and mechanically equivalent across all specified parameters. Both parts are pin contacts for the AMPLIMITE HDP-20 series with identical wire gauge (20-24 AWG), crimp termination, brass material, and gold flash finish. Direct substitution is supported.
Q: What is the primary reason for substituting the 5-66506-3?
A: The 5-66506-3 is classified as obsolete. The 205202-7 is an active product with current manufacturing support and confirmed inventory availability, eliminating supply chain discontinuity.
Q: Are there any compliance differences between these parts?
A: Both parts are RoHS compliant and carry identical MSL ratings of 1 (Unlimited). No compliance degradation occurs with substitution.
Q: Does the bulk packaging of the 205202-7 affect its electrical or mechanical performance?
A: No. Packaging format does not affect the electrical or mechanical properties of the contact. Bulk packaging may require adjustment to receiving, storage, and handling procedures but does not impact component performance or compatibility.
Q: Are both parts suitable for signal applications in AMPLIMITE HDP-20 connectors?
A: Yes. Both the 5-66506-3 and 205202-7 are specified for signal applications and are fully compatible with AMPLIMITE HDP-20 connector assemblies.
Q: What wire gauges are supported by the 205202-7?
A: The 205202-7 supports 20-24 AWG wire, identical to the 5-66506-3 specification.
