Breaker Type: Thermal (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)
Product Status: Active (required for current sourcing)
RoHS Status: ROHS3 Compliant (required for regulatory compliance)

All substitute parts listed below meet these criteria. Parts are grouped into two series categories: TA35 series (4435.0088, 4435.0009, 4435.0125) and TA45 series (4430.0706, 4430.2421, 4430.2437, 4430.3021, 4430.3216, 4430.34, 4430.3676, 4430.3742). Both series maintain identical electrical specifications and mechanical form factors, permitting direct substitution within applications.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring current availability and regulatory alignment with the primary part 4435.0088. Selection among TA35 series alternatives (4435.0009, 4435.0125) provides direct series compatibility. Selection among TA45 series alternatives (4430.0706, 4430.2421, 4430.2437, 4430.3021, 4430.3216, 4430.34, 4430.3676, 4430.3742) offers expanded inventory availability while maintaining identical electrical and mechanical specifications.

Parts with higher inventory levels (4435.0125 at 1191 pcs, 4435.0009 at 1147 pcs, 4430.3021 at 1062 pcs, 4430.2437 at 1010 pcs) provide greater supply security for production planning. Compliance certifications listed for select TA45 parts (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) indicate additional regional approval pathways where applicable to end-use requirements.

Frequently Asked Questions (FAQ)

Q: Can TA45 series parts substitute for TA35 series parts? A: Yes. Both TA35 and TA45 series maintain identical electrical ratings (4A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (rocker), and pole count (2). Series designation reflects internal design evolution while preserving form, fit, and function compatibility.

Q: What parameters must match exactly for substitution? A: Current rating (4A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and pole count (2) must remain unchanged. Deviations in any of these parameters disqualify a part from substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the primary part 4435.0088.

Q: Do substitute parts carry the same certifications? A: Select TA45 parts (4430.0706, 4430.2421, 4430.2437, 4430.3021, 4430.3216, 4430.3742) list approval agencies including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Verify specific certification requirements for your application region before final selection.

Q: How should inventory levels influence part selection? A: Inventory levels indicate supply availability for production scheduling. Higher inventory parts (4435.0125, 4435.0009, 4430.3021, 4430.2437) support larger production runs and reduce lead-time risk. Lower inventory parts may require longer procurement cycles.

Q: Is panel mount configuration identical across all substitute parts? A: Yes. All substitute parts feature identical panel mount configuration, ensuring mechanical compatibility with existing PCB layouts and enclosure designs.
