Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APEM 5646CDB are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical circuit configuration (DPDT), switch function (On-On), current rating (0.4VA AC/DC), and voltage ratings (20V AC/DC).

Mechanical Compatibility: Substitute parts share the same mounting type (Panel Mount), termination style (Solder Lug), bushing thread specification (1/4-40), and compatible panel cutout dimensions (circular 6.35mm - 6.50mm diameter).

Environmental & Compliance: All substitute parts are ROHS3 compliant, non-illuminated, feature epoxy sealed terminals, and maintain MSL rating of 1 (Unlimited).

Allowed Parameter Variations: Actuator length, operating temperature range, electrical life cycle rating, actuator material finish, and REACH status may vary between substitutes while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for equivalent circuit applications. Selection between APEM 5646CDB, E-Switch 100DP1T1B1M1REH, and C&K 7201SYZBE depends on specific application requirements:

APEM 5646CDB provides the widest operating temperature range (-40°C to 85°C) and REACH Unaffected status, suitable for applications requiring extended low-temperature performance.

E-Switch 100DP1T1B1M1REH offers a compact alternative with identical electrical specifications and REACH Unaffected status, with operating temperature range of -30°C to 85°C.

C&K 7201SYZBE delivers the highest electrical life rating (100,000 cycles) and maintains ROHS3 compliance, though REACH status is listed as Affected. This part is suitable for high-cycle applications where extended operational life is prioritized.

Panel cutout diameter variations (6.35mm versus 6.50mm) require verification against existing panel mounting holes to ensure mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M1REH replace APEM 5646CDB in all applications?

A: E-Switch 100DP1T1B1M1REH is electrically equivalent with identical circuit configuration, current rating, and voltage specifications. The operating temperature range is -30°C to 85°C compared to APEM's -40°C to 85°C. Panel cutout diameter differs (6.35mm versus 6.50mm), requiring verification of existing mounting hole dimensions.

Q: What is the difference in electrical life between these parts?

A: APEM 5646CDB is rated for 50,000 cycles, E-Switch 100DP1T1B1M1REH for 40,000 cycles, and C&K 7201SYZBE for 100,000 cycles. Selection should align with application duty cycle requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all three parts are ROHS3 compliant. APEM 5646CDB and E-Switch 100DP1T1B1M1REH are REACH Unaffected, while C&K 7201SYZBE is REACH Affected.

Q: Do panel cutout dimensions affect substitution?

A: Panel cutout diameter specifications are 6.50mm for APEM 5646CDB and 6.35mm for both E-Switch and C&K parts. Existing panel mounting holes must accommodate these dimensions. All parts share identical 1/4-40 bushing thread specification.

Q: Which substitute part offers the best long-term reliability?

A: C&K 7201SYZBE provides the highest electrical life rating at 100,000 cycles, compared to 50,000 cycles for APEM and 40,000 cycles for E-Switch. Selection should be based on specific application cycle requirements and environmental operating conditions.
