Substitute Part Grouping Explanation

Substitution logic for the 34ASP33B1M1RT is based on strict alignment of electrical and mechanical parameters. The following criteria determine valid substitutes:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Termination style must be Solder Lug
• Operating temperature range must encompass -30°C ~ 85°C
• Electrical life must be minimum 40,000 cycles

Electrical Rating Criteria:

• Current rating must be equal to or greater than 0.4VA
• Voltage ratings (AC and DC) must be equal to or greater than 20V

Compliance Criteria:

• RoHS status must be compliant (RoHS Compliant or ROHS3 Compliant)
• Moisture sensitivity level must be 1 (Unlimited)

Substitutes are grouped into two categories based on electrical rating alignment:

Group 1 - Direct Electrical Equivalents (0.4VA @ 20V): Parts with identical current and voltage ratings, requiring no circuit re-evaluation.

Group 2 - Higher-Rated Substitutes (5A @ 120V AC / 28V DC): Parts with elevated electrical ratings that provide enhanced capacity for the same mechanical interface. These substitutes are electrically compatible but operate at higher performance margins.

Parameter Comparison

Engineering Selection Recommendations

100SP3T1B1M1REH (E-Switch) - Direct Equivalent Substitute

The 100SP3T1B1M1REH is a direct electrical and mechanical equivalent to the 34ASP33B1M1RT. Both parts share identical current (0.4VA), voltage (20V AC/DC), circuit configuration (SPDT), and mechanical interface specifications. The E-Switch part features epoxy sealed terminals and ROHS3 compliance, meeting all regulatory requirements. The primary difference is actuator length (10.41mm versus 13.97mm), which does not affect electrical function or panel mounting compatibility. This substitute is suitable for direct replacement in existing designs without circuit modification.

7103P3YZQE and 7103SYZQE (C&K) - Higher-Rated Substitutes

The C&K 7103 series parts (7103P3YZQE and 7103SYZQE) provide elevated electrical ratings of 5A at 120V AC and 28V DC, compared to the 0.4VA at 20V specification of the main part. Both C&K substitutes maintain identical mechanical interfaces (panel cutout, bushing thread, solder lug termination) and operating temperature range. The 7103P3YZQE features a flat anti-rotation actuator, while the 7103SYZQE retains a standard round actuator. Both are ROHS3 compliant with epoxy sealed terminals. These substitutes are electrically compatible for applications where higher switching capacity is beneficial or required, though they operate at higher performance margins than the original specification.

Compliance Considerations

All substitute parts maintain Active product status and meet MSL 1 (Unlimited) moisture sensitivity requirements. The E-Switch 100SP3T1B1M1REH is ROHS3 compliant. The C&K 7103 series parts are ROHS3 compliant but carry REACH Affected status, requiring verification against specific REACH substance restrictions in regulated markets. The original 34ASP33B1M1RT is RoHS Compliant with REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T1B1M1REH replace the 34ASP33B1M1RT in all applications?

A: Yes, the 100SP3T1B1M1REH is a direct electrical and mechanical equivalent. Both parts share identical current ratings (0.4VA), voltage ratings (20V AC/DC), circuit configuration (SPDT), panel cutout dimensions (6.35mm), bushing thread (1/4-40), and operating temperature range (-30°C to 85°C). The actuator length difference (10.41mm versus 13.97mm) does not affect electrical function or panel mounting compatibility.

Q: What is the difference between the 7103P3YZQE and 7103SYZQE substitutes?

A: Both C&K parts share identical electrical ratings (5A at 120V AC / 28V DC) and mechanical specifications. The primary difference is actuator type: the 7103P3YZQE features a flat anti-rotation actuator (11.43mm length), while the 7103SYZQE has a standard round actuator (10.67mm length). Both are mechanically compatible with the original panel mount interface.

Q: Can I use the C&K 7103 series parts as direct replacements for the 34ASP33B1M1RT?

A: The C&K 7103 series parts are mechanically compatible but electrically rated higher (5A at 120V AC / 28V DC versus 0.4VA at 20V). They are suitable for applications where the original part is specified, as higher electrical ratings provide additional capacity margin. However, circuit design must accommodate the higher voltage and current ratings if the application operates at these elevated levels.

Q: Are there packaging differences between these substitutes?

A: The 34ASP33B1M1RT is packaged in standard format (967 Pcs inventory noted). The 100SP3T1B1M1REH is packaged in Bulk (1976 Pcs inventory). The C&K 7103P3YZQE and 7103SYZQE are packaged in Bulk (980 Pcs and 1749 Pcs inventory respectively). Packaging format does not affect electrical or mechanical compatibility.

Q: What compliance differences exist between the main part and substitutes?

A: The 34ASP33B1M1RT is RoHS Compliant with REACH Unaffected status. The 100SP3T1B1M1REH is ROHS3 Compliant with REACH Unaffected status. The C&K 7103 series parts are ROHS3 Compliant but carry REACH Affected status. All parts maintain MSL 1 (Unlimited) and EAR99 ECCN classification. REACH Affected status requires verification against specific substance restrictions in regulated markets.

Q: Do all substitutes maintain the 40,000 electrical cycle rating?

A: Yes, all substitute parts (100SP3T1B1M1REH, 7103P3YZQE, and 7103SYZQE) maintain the 40,000 electrical cycle rating specified for the 34ASP33B1M1RT, ensuring equivalent durability performance.

Q: What is the significance of epoxy sealed terminals on the E-Switch and C&K substitutes?

A: Epoxy sealed terminals provide enhanced environmental protection for solder lug connections, improving resistance to moisture and contamination. This feature is present on the 100SP3T1B1M1REH and both C&K 7103 series parts but is not specified for the original 34ASP33B1M1RT. This represents an enhancement rather than a compatibility concern.
