Frequently Asked Questions (FAQ)

Q: Can HR25A-9P-20SC be used as a direct replacement for HR25-9P-20SC(72)?

A: Yes. Both connectors maintain identical specifications for connector type, position count (20), shell size (9), mounting configuration (free hanging in-line), fastening mechanism (push-pull), shell material (zinc alloy with nickel finish), and operating temperature range (-25°C ~ 85°C). The HR25A-9P-20SC is the active product equivalent.

Q: What is the primary difference between HR25-9P-20SC(72) and HR25A-9P-20SC?

A: The HR25A-9P-20SC includes integrated backshell, cable clamp, and strain relief features. The HR25-9P-20SC(72) is shielded, while the HR25A-9P-20SC is unshielded. The HR25A series represents the current active product line, while HR25-9P-20SC(72) is obsolete.

Q: Are there packaging differences between these parts?

A: The HR25-9P-20SC(72) is supplied in standard packaging. The HR25A-9P-20SC is supplied in bulk packaging. Both maintain identical electrical and mechanical form factors.

Q: What compliance certifications apply to both parts?

A: Both connectors meet UL94 V-0 material flammability requirements and operate across the -25°C ~ 85°C temperature range. The HR25A-9P-20SC carries RoHS compliance status.

Q: Are contacts included with these connector housings?

A: No. Both the HR25-9P-20SC(72) and HR25A-9P-20SC are supplied as housings only. Contacts must be sourced separately and crimped into the connector assembly.
