Substitute Part Grouping Explanation

Substitution for the AR16-HZW/T is determined by strict equivalence in the following critical parameters:

16-position configuration with 2 x 8 arrangement
0.3" (7.62mm) row spacing
0.100" (2.54mm) pitch for both mating and post contacts
Gold-plated mating contacts
Through-hole wire wrap termination
Beryllium copper or brass post contact material
Operating temperature range of at least -40°C to 105°C
Current rating of at least 1 A
UL94 V-0 flammability rating

All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications originally designed for the AR16-HZW/T.

Engineering Selection Recommendations

AR 16-HZW/TN (Assmann WSW Components) is the primary direct substitute. This part maintains identical electrical and mechanical specifications to the AR16-HZW/T while offering active product status and ROHS3 compliance. The only difference is packaging format (tube versus unspecified). This represents the lowest-risk substitution path.

123-43-316-41-001000 (Mill-Max Manufacturing Corp.) provides an alternative from a different manufacturer with extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. The post contact material differs (brass alloy versus beryllium copper), and contact resistance is not specified. This part is suitable for applications requiring broader temperature performance.

16-3508-20 (Aries Electronics) offers ROHS3 compliance and active status with a wider operating temperature range (-55°C to 105°C). The housing material is polyamide (PA46) nylon glass-filled rather than polyester. This option is available in bulk packaging and maintains the required 3 A current rating.

D0816-42 (Harwin Inc.) provides the widest operating temperature range (-55°C to 125°C) and ROHS3 compliance. However, the current rating is reduced to 1 A and contact resistance is specified at 10 mOhm (higher than the original 4 mOhm). This part is suitable only for applications with lower current requirements.

For new designs or production requiring RoHS compliance, AR 16-HZW/TN is recommended as the primary choice. For applications with extended temperature requirements, 123-43-316-41-001000 or D0816-42 are appropriate alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use D0816-42 as a direct replacement for AR16-HZW/T?

A: D0816-42 is mechanically and electrically compatible for most applications. However, the current rating is 1 A compared to the original 3 A, and contact resistance is 10 mOhm versus 4 mOhm. Use this part only if your application current requirements do not exceed 1 A.

Q: What is the difference between AR16-HZW/T and AR 16-HZW/TN?

A: Both parts are functionally identical with the same electrical and mechanical specifications. The primary differences are product status (obsolete versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). Packaging format also differs (unspecified versus tube).

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The original AR16-HZW/T is RoHS non-compliant. If RoHS compliance is required for your application, any of the substitute parts are suitable.

Q: Do the substitute parts have the same operating temperature range?

A: No. The original AR16-HZW/T operates from -40°C to 105°C. Substitute parts offer either the same range or extended ranges up to -55°C to 125°C. Extended temperature range substitutes are suitable for all applications designed for the original part.

Q: What is the difference in contact material between the post contacts?

A: The original AR16-HZW/T uses beryllium copper for post contacts. Most substitutes use brass or brass alloy. Both materials are suitable for wire wrap termination and maintain electrical compatibility.

Q: Which substitute part should I choose for new production?

A: AR 16-HZW/TN is the recommended choice for new production as it maintains identical specifications to the original part while offering active product status and ROHS3 compliance. For applications requiring extended temperature performance, 123-43-316-41-001000 or D0816-42 are appropriate alternatives.

Q: Are there packaging differences between substitute parts?

A: Yes. AR 16-HZW/TN is supplied in tube packaging, while 16-3508-20 and D0816-42 are supplied in bulk packaging. Tube packaging is typically preferred for automated assembly processes.
