APD1246DN-A Equivalent & Substitute Parts

Part Overview

The APD1246DN-A is a 30mm LED panel indicator manufactured by IDEC, designed for 240V AC applications with screw terminal connections. This component features an amber lens with a round domed top, IP65/NEMA 4X/13 ingress protection rating, and ROHS3 compliance. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing system maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APD1246DN-A is determined by strict alignment across the following critical parameters:

• Panel cutout dimensions: 1.18" (30.0mm) round
• Voltage rating: 240V AC
• Lens color: Amber
• Lens style: Round with domed top
• Termination style: Screw terminal
• Ingress protection rating: IP65, NEMA 4X, 13
• Component type: LED
• RoHS compliance: ROHS3 Compliant

Both identified substitutes—APD1246DNUA and APD1QM4DNUA—meet all these parameters. The primary distinction between substitutes lies in their product status (both active versus the obsolete original) and their respective series designations (TWND series for both substitutes versus TWTD series for the original).

Parameter Comparison

Engineering Selection Recommendations

Both APD1246DNUA and APD1QM4DNUA are suitable replacements for the obsolete APD1246DN-A based on complete parameter alignment. Selection between the two active substitutes should be based on:

APD1246DNUA is classified as a direct manufacturer substitute, sharing the same base product number (APD1246) as the original part. This designation indicates the closest functional continuity within the IDEC product line.

APD1QM4DNUA is classified as a parametric equivalent, operating under a different base product number (APD1QM4) while maintaining identical electrical and mechanical specifications. This part represents an alternative design approach within the same functional category.

Both substitutes carry ROHS3 compliance and EAR99 ECCN classification, meeting current regulatory requirements. Inventory availability is documented for both options, with APD1246DNUA offering the highest stock level at 981 units.

Frequently Asked Questions (FAQ)

Q: Can APD1246DNUA and APD1QM4DNUA be used interchangeably with APD1246DN-A?

A: Yes. Both substitutes match all critical parameters: 30mm round panel cutout, 240V AC rating, amber domed lens, screw terminal connection, and IP65/NEMA 4X/13 protection. Physical and electrical compatibility is confirmed.

Q: What is the difference between a direct substitute and a parametric equivalent?

A: APD1246DNUA is a direct substitute sharing the same base product number (APD1246) as the original. APD1QM4DNUA is a parametric equivalent with a different base product number (APD1QM4) but identical functional specifications. Both are electrically and mechanically compatible.

Q: Are there packaging differences between the substitutes?

A: Both substitutes are supplied in bulk packaging. The original APD1246DN-A packaging specification was not provided in the technical data.

Q: Do the substitutes maintain the same ingress protection rating?

A: Yes. Both APD1246DNUA and APD1QM4DNUA maintain IP65, NEMA 4X, and NEMA 13 ingress protection ratings, identical to the original part.

Q: Are both substitutes currently in production?

A: Yes. Both APD1246DNUA and APD1QM4DNUA are classified as active products, unlike the obsolete APD1246DN-A. Current inventory is available for both options.
