Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 22-4501-30 is determined by the following critical parameters:

• Position Count and Configuration: 22 positions in 2 x 11 arrangement (non-negotiable)
• Row Spacing: 0.4" (10.16mm) center-to-center distance (non-negotiable)
• Pitch - Mating: 0.100" (2.54mm) (non-negotiable)
• Mounting Type: Through Hole (non-negotiable)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• Current Rating: Minimum 1.0 A (substitute must meet or exceed)
• Compliance: ROHS3 Compliant and RoHS3 Compliant status

The Preci-Dip 122-87-422-41-001101 meets all critical dimensional and electrical requirements for substitution. Variations in contact finish material (gold vs. tin), frame design (open vs. closed), and post length represent acceptable trade-offs within the DIP socket category, provided the core functional parameters remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The Preci-Dip 122-87-422-41-001101 is a qualified substitute for the obsolete Aries Electronics 22-4501-30. Both components maintain identical critical dimensional specifications (22 positions, 0.4" row spacing, 0.100" mating pitch) and are rated for the same operating temperature range (-55°C ~ 125°C). Both components carry ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory alignment.

The substitute part is currently in active production status, providing supply chain continuity for applications requiring 22-position DIP sockets. The current rating of the substitute (1.0 A) is lower than the original part (1.5 A); applications requiring the full 1.5 A rating must be evaluated against actual circuit requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 122-87-422-41-001101 be used as a direct replacement for the Aries 22-4501-30?

A: Yes, for applications where the 1.0 A current rating is sufficient. Both parts share identical position count, row spacing, mating pitch, and operating temperature range. The substitute is currently in active production, addressing the obsolescence of the original part.

Q: What are the differences between the tin and gold contact finishes?

A: The original part uses tin contact finish on both mating and post surfaces, while the substitute uses gold on mating contacts and tin on post contacts. Both finishes are suitable for wire wrap termination. Contact finish selection depends on specific application requirements for corrosion resistance and contact reliability.

Q: Does the difference in termination post length affect compatibility?

A: Post length differences (0.690" vs. 0.370") affect board layout and wire wrap depth requirements. The shorter post length of the substitute may require adjustment to wire wrap tooling and board design. Verify post length compatibility with your specific PCB design before implementation.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the original and substitute parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the significance of the frame design difference (closed vs. open)?

A: The original part features a closed frame design, while the substitute uses an open frame design. Frame design affects mechanical stability and insertion force characteristics. Verify that your insertion equipment and application requirements are compatible with the open frame design of the substitute.
