Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSS-89STB is determined by the following critical parameters:

Functional Equivalence Criteria:

• Output Type: SPST-NO configuration
• Actuator Material: Magnet-based actuation
• Type: Ball Switch mechanism
• Termination Style: Wire Leads

Regulatory & Compliance Alignment:

• REACH compliance status
• ECCN classification
• Moisture Sensitivity Level (MSL) rating

The MSS-63S qualifies as a manufacturer-recommended substitute based on identical functional parameters (SPST-NO output, magnetic actuation, ball switch type, wire lead termination, and module packaging). Both components operate within the same electrical and mechanical specifications, enabling direct functional replacement in applications designed for the MSS-89STB.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MSS-63S

The MSS-63S is the manufacturer-recommended equivalent for the obsolete MSS-89STB. Selection of this substitute is based on:

1. Functional Parity: Identical output configuration (SPST-NO), actuator type (magnet), and switch mechanism (ball switch) ensure electrical and mechanical compatibility.

2. Active Product Status: The MSS-63S maintains active product status with current manufacturing support and documented inventory availability (774 Pcs), whereas the MSS-89STB is obsolete.

3. Regulatory Compliance: Both components share EAR99 ECCN classification. The MSS-63S additionally carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements.

4. Packaging Compatibility: Both components utilize module-based packaging with wire lead termination, supporting identical PCB integration and circuit design approaches.

For applications currently utilizing the MSS-89STB, direct substitution with the MSS-63S is supported without circuit redesign or functional modification.

Frequently Asked Questions (FAQ)

Q: Can the MSS-63S directly replace the MSS-89STB in existing designs?

A: Yes. Both components share identical functional specifications: SPST-NO output, magnetic ball switch mechanism, wire lead termination, and module packaging. Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The MSS-89STB is obsolete, while the MSS-63S maintains active product status with current manufacturing availability. The MSS-63S also carries ROHS3 compliance certification. Functionally, both components are equivalent.

Q: Are there packaging differences between MSS-89STB and MSS-63S?

A: The MSS-89STB is supplied in module packaging without specified packaging format. The MSS-63S is supplied in bag packaging. Both maintain identical module case configuration and wire lead termination, ensuring compatibility in circuit applications.

Q: What regulatory certifications apply to these components?

A: Both components are classified under ECCN EAR99 and carry REACH Unaffected status (MSS-89STB) or equivalent compliance. The MSS-63S additionally meets ROHS3 requirements, supporting compliance with modern environmental regulations.

Q: Is inventory availability a consideration for part selection?

A: Yes. The MSS-89STB shows 913 Pcs in stock as new original inventory. The MSS-63S shows 774 Pcs in stock. For new designs or long-term production, the MSS-63S is recommended due to active product status and ongoing manufacturing support.
