Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E15-1-11 is determined by the following critical parameters:

• Shaft Size: 0.250" (6.35mm) — mechanical interface requirement
• Number of Turns: 10 — functional resolution specification
• RoHS Compliance: ROHS3 Compliant — regulatory requirement
• REACH Status: REACH Unaffected — regulatory requirement
• ECCN Classification: EAR99 — export control alignment
• HTSUS Code: 8533.90.8000 — tariff classification alignment

The substitute part 15A11B10 meets all critical parameters. While the scale dial material differs (metal versus aluminum), both materials satisfy the functional and mechanical requirements for this component category.

Parameter Comparison

Engineering Selection Recommendations

The 15A11B10 from Vishay Spectrol is a direct functional equivalent to the E15-1-11. Both components share identical shaft size (0.250"), turn count (10), series designation (15), and regulatory compliance profiles (ROHS3, EAR99, HTSUS 8533.90.8000).

The primary distinction is product status: the E15-1-11 is obsolete while the 15A11B10 is active. For new designs or long-term procurement strategies, the 15A11B10 is the appropriate selection. The 15A11B10 offers significantly higher inventory availability (351,200 pieces versus 629 pieces), supporting sustained supply chain requirements.

Frequently Asked Questions (FAQ)

Q: What makes the 15A11B10 a suitable substitute for the E15-1-11?

A: Both components share the critical mechanical and functional parameters: 0.250" (6.35mm) shaft size, 10-turn configuration, and Series 15 designation. Both maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory and interface compatibility.

Q: Does the difference between aluminum and metal scale dials affect substitution?

A: Both aluminum and metal scale dials satisfy the functional requirements for this component category. The material difference does not impact mechanical interface or electrical performance for dial digital components with key.

Q: Why is the 15A11B10 listed as active while the E15-1-11 is obsolete?

A: Product status reflects manufacturer support and production status. The E15-1-11 is no longer manufactured by Precision Electronics Corporation. The 15A11B10 remains in active production by Vishay Spectrol, ensuring ongoing availability and support.

Q: Are there packaging considerations when selecting between these parts?

A: The E15-1-11 packaging is unspecified in available documentation. The 15A11B10 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications before finalizing component selection.

Q: Can the 15A11B10 be used in applications originally designed for the E15-1-11?

A: Yes. The 15A11B10 meets all specified mechanical and regulatory parameters required for direct substitution in applications designed for the E15-1-11.
