Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34EWMSP34M6RT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Surface Mount, Right Angle
• Termination style: Gull Wing
• Operating temperature range: -30°C to 85°C
• Electrical life: 30,000 cycles minimum

Allowable Variations:

• Actuator length: 6.10mm to 6.70mm (within mechanical envelope constraints)
• Ingress protection: IP57 or IP67 (both provide dust and water protection)
• Actuator material: Brass chrome-plated or polyamide alternatives
• Terminal sealing: Epoxy sealed or equivalent protection
• Moisture sensitivity level: MSL 1 or MSL 3
• RoHS compliance: RoHS Compliant or ROHS3 Compliant

The two substitute parts listed below meet all mandatory parameters and fall within allowable variations.

Parameter Comparison

Engineering Selection Recommendations

ET03MD1SAPE (C&K) - Primary Substitute:

The ET03MD1SAPE represents the closest functional equivalent to the 34EWMSP34M6RT. Both parts feature epoxy sealed terminals, brass chrome-plated actuators, and MSL 1 moisture sensitivity ratings. The ET03MD1SAPE maintains ROHS3 compliance and carries 1388 units in inventory. The primary difference is the reduced actuator length (6.10mm versus 6.70mm) and IP57 ingress protection rating versus IP67. These variations remain within acceptable mechanical and environmental tolerances for equivalent circuit applications.

ET03M3D1SAPE (C&K) - Secondary Substitute:

The ET03M3D1SAPE provides functional equivalence with the trade-off of a polyamide actuator material and MSL 3 moisture sensitivity rating. This part features a black antistatic actuator and maintains ROHS3 compliance. The MSL 3 rating requires controlled storage conditions (168-hour maximum exposure to 85°C/85% RH). This substitute is suitable for applications where actuator material flexibility is acceptable and moisture-controlled storage environments are available. Inventory availability is highest at 1672 units.

Both substitute parts satisfy the mandatory electrical and mechanical parameters. Selection between them depends on specific application requirements regarding actuator material properties and moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can ET03MD1SAPE and ET03M3D1SAPE be used interchangeably with 34EWMSP34M6RT?

A: Both C&K parts meet the core electrical specifications (SPDT, 0.4VA, 20V, On-Off-On function) and mechanical requirements (surface mount, right angle, gull wing termination). The ET03MD1SAPE is the closer match due to identical actuator material and MSL rating. The ET03M3D1SAPE introduces material and moisture sensitivity differences that may affect suitability depending on application environment and storage conditions.

Q: What is the significance of the actuator length difference (6.70mm vs. 6.10mm)?

A: The 0.6mm reduction in actuator length affects the mechanical envelope and panel cutout clearance. Design verification is necessary to confirm that the shorter actuator length does not interfere with surrounding components or panel geometry. This parameter must be evaluated within the specific PCB layout and enclosure design.

Q: Why does ET03M3D1SAPE have an MSL 3 rating while the others are MSL 1?

A: MSL (Moisture Sensitivity Level) indicates the maximum exposure time to 85°C/85% relative humidity before component damage risk increases. MSL 1 allows unlimited exposure, while MSL 3 limits exposure to 168 hours. ET03M3D1SAPE requires controlled storage and handling procedures. This affects supply chain logistics and manufacturing floor conditions but does not impact electrical performance in the final application.

Q: Are there packaging differences between these parts?

A: The 34EWMSP34M6RT is supplied in bulk packaging, while both C&K substitutes (ET03MD1SAPE and ET03M3D1SAPE) are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and may require different handling equipment or manual processing for bulk applications.

Q: What is the difference between IP67 and IP57 ingress protection ratings?

A: IP67 provides complete dust protection and waterproofing up to temporary immersion (1 meter, 30 minutes). IP57 provides dust protection and waterproofing up to water jets from any direction. Both ratings exceed typical environmental requirements for sealed electronic enclosures. The difference is relevant only for applications involving direct immersion or high-pressure water exposure.

Q: Do all three parts comply with RoHS regulations?

A: Yes. The 34EWMSP34M6RT carries RoHS Compliant status. Both C&K substitutes carry ROHS3 Compliant status, which represents the current RoHS 3 directive compliance standard. Both compliance levels are acceptable for applications requiring RoHS adherence.
