Equivalent & Substitute Parts Reference for DA12 (APEM Inc.)

Part Overview

The DA12 is a DIP switch manufactured by APEM Inc., configured as SPST with 12 positions. It features a through-hole, right angle, slide actuator, and supports a maximum current rating of 50mA at 24VDC. The DA12 is currently obsolete, necessitating the identification of direct equivalent or substitute models for ongoing production support or replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

The substitute part NDA-12-V is identified strictly based on matching the following allowed parameters: circuit type (SPST), number of positions (12), actuator type (slide, standard), actuator level (raised), mounting type (through hole, right angle), termination style (PC pin), pitch (0.100" (2.54mm), full), height above board, operating temperature range, voltage rating (24VDC), electrical life, RoHS and REACH compliance, and moisture sensitivity level. Divergence in parameters such as current rating and minor dimensional variations are documented.

Parameter Comparison

Engineering Selection Recommendations

Selection of NDA-12-V as a substitute for DA12 is based solely on the product status (active replacement for obsolete device), matching compliance certifications (ROHS3, REACH, MSL), and shared category qualifications. The NDA-12-V is the available model with equivalent configuration and regulatory approvals.

Frequently Asked Questions (FAQ)

Q1: What determines if NDA-12-V is a direct substitute for DA12?
A1: Substitution is determined by matching circuit type, number of positions, voltage rating, actuator configuration, mounting and termination style, pitch, operating temperature, and all compliance criteria provided.

Q2: Are there any notable dimensional differences between DA12 and NDA-12-V?
A2: Length differs slightly: DA12 is 1.259" (31.98mm) while NDA-12-V is 1.250" (31.75mm). All other dimensional parameters match.

Q3: Does current rating affect direct substitution?
A3: DA12 features 50mA, NDA-12-V features 25mA. This is a documented parameter difference.

Q4: Are both parts suitable for through-hole, right angle PCB mounting?
A4: Yes, both utilize the same mounting and termination style.

Q5: Do both models share the same compliance certificates?
A5: Both are ROHS3 compliant, REACH unaffected, and assigned MSL 1 (Unlimited).

Q6: What are the operating temperature ranges for these DIP switches?
A6: Both operate within -20°C ~ 70°C.

Q7: Is there any difference in electrical life?
A7: Both parts specify an electrical life of 2,000 cycles.

Q8: Is the NDA-12-V suitable where epoxy sealed terminals are required?
A8: Only DA12 specifies epoxy sealed terminals in the provided parameters. NDA-12-V does not specify this feature.
