Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit configuration (SPDT required)
• Switch function (On-Mom required)
• Actuator type (Round pin plunger required)
• Mounting type (Through hole required)
• Termination style (PC pin required)
• Operating position (0.330" / 8.4mm required)
• Current and voltage ratings (must meet or exceed application requirements)
• Temperature operating range (must encompass application environment)
• Form factor compatibility (physical dimensions and pin spacing)

The following parts meet these substitution criteria for the AVL34053:

Direct Substitutes (Equivalent Ratings):

• DB1C-C1AA (ZF Electronics) - Matching 5A/125V AC rating, active status
• DB2CC1AA (ZF Electronics) - Higher current capacity (10A AC), active status

Functional Alternatives (Higher Voltage Rating):

• 41SM25-H2 (Honeywell) - 11A AC / 5A DC at 250V AC, active status
• 11SM8423-H2 (Honeywell) - 5A at 250V AC, obsolete status
• 1SM33-H2 (Honeywell) - 5A at 250V AC, obsolete status

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

DB1C-C1AA and DB2CC1AA from ZF Electronics are active production parts with ROHS3 compliance matching the AVL34053. DB1C-C1AA provides equivalent 5A/125V AC ratings with extended DC voltage capability (48V). DB2CC1AA offers increased current capacity at 10A AC for applications requiring higher current switching while maintaining 125V AC rating.

Secondary Alternatives (Higher Voltage Applications):

41SM25-H2 from Honeywell is an active production part suitable for 250V AC applications requiring 11A AC switching capacity. This part provides extended voltage and current ratings with RoHS compliance, though electrical life data is not specified.

Obsolete Alternatives (Legacy System Replacement Only):

11SM8423-H2 and 1SM33-H2 from Honeywell are obsolete production parts. These should be considered only for direct replacement in existing systems where supply of active alternatives is constrained. Both parts provide 250V AC rating with RoHS compliance but are no longer in active manufacture.

Frequently Asked Questions (FAQ)

Q: Can DB1C-C1AA directly replace AVL34053 in all applications?

A: DB1C-C1AA is mechanically and electrically compatible for applications operating at 5A or less at 125V AC. The part shares identical operating position (0.330"), actuator type, mounting configuration, and termination style. DC current rating differs (1A versus 5A), so DC applications must be evaluated against the 1A DC limit of DB1C-C1AA.

Q: What is the difference between DB2CC1AA and DB1C-C1AA?

A: DB2CC1AA is rated for 10A AC at 125V, compared to DB1C-C1AA at 5A AC. Both share identical mechanical form factor and mounting characteristics. DB2CC1AA has higher operating force (250gf versus 150gf), which may affect actuator feel in manual applications.

Q: Why are Honeywell parts listed as obsolete?

A: 11SM8423-H2 and 1SM33-H2 are no longer in active production by Honeywell. These parts are included for reference in legacy system documentation and component traceability. Active production alternatives from ZF Electronics and Panasonic are preferred for new designs.

Q: Can 41SM25-H2 be used in a 125V AC circuit?

A: Yes. 41SM25-H2 is rated for 250V AC, which exceeds the 125V AC requirement. The part is suitable for 125V AC applications. However, the higher operating force (113gf versus 150gf) and different electrical life characteristics should be considered for the specific application.

Q: Are all substitute parts RoHS compliant?

A: Yes. AVL34053, DB1C-C1AA, and DB2CC1AA are ROHS3 compliant. 41SM25-H2, 11SM8423-H2, and 1SM33-H2 are RoHS compliant. All parts meet environmental compliance requirements for current manufacturing standards.

Q: What is the impact of different operating force values?

A: Operating force determines the manual actuation effort required. AVL34053 and DB1C-C1AA both specify 150gf. DB2CC1AA requires 250gf (higher effort), while Honeywell parts range from 99gf to 141gf (lower effort). Application ergonomics and mechanical design must accommodate these differences.

Q: Can these parts be used interchangeably in PCB designs?

A: All substitute parts share identical through-hole PC pin termination and 0.330" operating position. PCB footprints are compatible. Physical dimensions and pin spacing must be verified against the specific PCB layout before implementation.
