Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SZX-SMF-14N is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of Positions: 14
• Mounting Type: DIN Rail
• Termination Style: Screw Terminal
• Type: Socket

These parameters define the physical and electrical interface requirements. Parts meeting all four criteria are classified as functional equivalents capable of direct substitution in applications originally designed for the SZX-SMF-14N.

The substitute part 27E894 satisfies all primary substitution criteria, establishing it as a valid equivalent for the SZX-SMF-14N in DIN rail relay socket applications.

Parameter Comparison

Engineering Selection Recommendations

SZX-SMF-14N Status Consideration: The SZX-SMF-14N is classified as obsolete. For new designs and ongoing procurement, the 27E894 is the appropriate selection due to its active product status and current manufacturing availability.

Compliance Alignment: Both parts maintain export compliance under ECCN EAR99 classification. The 27E894 carries ROHS3 compliance, representing current regulatory standards. Both parts are suitable for applications requiring RoHS-compliant components.

Availability: The 27E894 demonstrates active inventory status with 2946 units available, compared to the SZX-SMF-14N's obsolete classification. For procurement planning, the 27E894 provides supply chain continuity.

Functional Equivalence: The 27E894 maintains identical electrical and mechanical interface specifications: 14-position configuration, DIN rail mounting, and screw terminal termination. Direct substitution is supported by parameter alignment.

Frequently Asked Questions (FAQ)

Q: Can the 27E894 directly replace the SZX-SMF-14N in existing installations?

A: Yes. Both parts share identical specifications for number of positions (14), mounting type (DIN rail), and termination style (screw terminal). The 27E894 is functionally equivalent and supports direct substitution.

Q: What is the significance of the SZX-SMF-14N being classified as obsolete?

A: Obsolete classification indicates the part is no longer manufactured by Honeywell. The 27E894, with active product status, represents the current equivalent available for procurement and future applications.

Q: Are there compliance differences between the two parts?

A: Both parts comply with RoHS standards and carry EAR99 export classification. The 27E894 carries ROHS3 compliance, reflecting current regulatory requirements. Both are suitable for regulated applications.

Q: What relay series are compatible with the 27E894?

A: The 27E894 is designed for use with PT, PTH, and KHA series relays. Compatibility with the original SZR-MY series should be verified through mechanical fit and electrical interface confirmation during integration.

Q: Does packaging differ between the two parts?

A: Both parts are supplied in bulk packaging. No special handling or packaging conversion is required for substitution.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: The SZX-SMF-14N carries MSL 1 (Unlimited), indicating no moisture sensitivity constraints. The 27E894 lists MSL as Not Applicable, indicating equivalent or superior moisture tolerance. Both are suitable for standard industrial environments.
