ERA-14EB752U Equivalent & Substitute Parts

Part Overview

The ERA-14EB752U is a 7.5 kOhms ±0.1% thin film chip resistor manufactured by Panasonic Electronic Components in 1210 (3225 Metric) package format with 0.25W power rating. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity. Substitute parts maintain the core electrical specifications while offering alternative manufacturers, enhanced ratings, or improved availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

Resistance value: 7.5 kOhms (exact match required)
Tolerance: ±0.1% or tighter (±0.05% acceptable as upgrade)
Package: 1210 (3225 Metric) or 1206 (3216 Metric) for space-constrained applications
Composition: Thin film construction
Temperature Coefficient: ±25ppm/°C

Secondary Considerations:

Power rating: 0.25W minimum (0.333W and 0.5W acceptable as upgrades)
Operating temperature range: -55°C minimum to 125°C minimum
RoHS3 compliance required for new designs
Moisture Sensitivity Level 1 (unlimited shelf life)

Substitutes are grouped into three categories: direct equivalents (same package and power rating), package variants (1206 alternative), and upgraded specifications (higher power rating or tighter tolerance).

Engineering Selection Recommendations

Direct Equivalents (Same Package, Power Rating, Active Status): RT1210BRD077K5L from YAGEO provides pin-for-pin compatibility with identical electrical specifications and active product status. This part is recommended for direct replacement in existing designs.

Upgraded Tolerance (Tighter Specification): RT1210WRD077K5L offers ±0.05% tolerance versus the original ±0.1%, providing enhanced precision for applications requiring tighter resistance tolerances while maintaining all other specifications.

Enhanced Power Rating (Same Package): RNCF1210BKE7K50, RNCF1210BTE7K50, TNPW12107K50BEEA, and TNPW12107K50BEEN provide increased power dissipation capability (0.333W or 0.5W) in the same 1210 package footprint. These are suitable for designs requiring thermal margin or higher power dissipation.

Package Variant (Smaller Footprint): ERA-8AEB752V from Panasonic uses the 1206 (3216 Metric) package, reducing board space by approximately 20% while maintaining electrical specifications. This option is applicable only when PCB layout permits package downsizing.

Compliance Consideration: TNPW12107K50BETA is RoHS non-compliant and REACH-affected. This part is not suitable for new designs requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB752V be used as a direct replacement for ERA-14EB752U? A: ERA-8AEB752V is electrically equivalent but uses a smaller 1206 package instead of 1210. It is suitable only if PCB layout accommodates the reduced footprint (3.20mm × 1.60mm versus 3.20mm × 2.50mm).

Q: What is the difference between TNPW12107K50BEEA and TNPW12107K50BEEN? A: Both parts are electrically and mechanically identical with 0.5W power rating, ±0.1% tolerance, and 1210 package. The suffix difference indicates packaging or manufacturing date code variants with no functional impact on substitution eligibility.

Q: Is RT1210WRD077K5L a suitable replacement? A: Yes. RT1210WRD077K5L provides tighter tolerance (±0.05% versus ±0.1%) in the same 1210 package with identical power rating and operating temperature range. This represents an upgrade in precision.

Q: Can higher power-rated parts (0.333W or 0.5W) be used in place of the 0.25W original? A: Yes. Higher power ratings are acceptable substitutes as they provide additional thermal margin. The circuit will function identically; the higher power rating simply indicates greater heat dissipation capability.

Q: Why is TNPW12107K50BETA not recommended? A: TNPW12107K50BETA is RoHS non-compliant and REACH-affected, making it unsuitable for new designs or applications requiring regulatory compliance documentation.

Q: Are all substitute parts available in tape and reel packaging? A: Yes. All listed substitute parts are supplied in tape and reel (TR) format, suitable for automated assembly processes.
