ERJ-S1TJ752U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TJ752U is a 7.5 kOhms ±5% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This part is rated for automotive applications under AEC-Q200 and features anti-sulfur construction. The part is currently active in production with 628 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements demand tighter tolerance specifications, or when alternative packaging formats are required for manufacturing optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TJ752U is determined by the following criteria:

Primary Substitution Parameters:

Resistance value: 7.5 kOhms (exact match required)
Power rating: 1W (exact match required)
Package / Case: 2512 (6432 Metric) (exact match required)
Composition: Thick Film (exact match required)
Automotive rating: AEC-Q200 (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)

Secondary Substitution Parameters (may vary):

Tolerance: ±5% or tighter (±1%)
Temperature coefficient: ±200ppm/°C or better (±100ppm/°C)
Packaging format: Tape & Reel (TR) or Cut Tape (CT)
Manufacturer: Panasonic, Vishay Dale, or Stackpole Electronics Inc

Parts meeting all primary parameters are direct functional equivalents. Tolerance improvements represent upgrades suitable for precision applications.

Engineering Selection Recommendations

Direct Equivalent (Preferred for Replacement):

CRCW25127K50JNEG (Vishay Dale) and RMCF2512JT7K50 (Stackpole Electronics Inc) are functionally equivalent to the ERJ-S1TJ752U with identical electrical specifications and active product status. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these options depends on packaging format requirements (Tape & Reel versus Cut Tape) and supply chain availability.

Upgrade Option (Enhanced Performance):

ERJ-S1TF7501U (Panasonic) provides tighter tolerance (±1% versus ±5%) and improved temperature coefficient (±100ppm/°C versus ±200ppm/°C) while maintaining identical resistance, power rating, package, and operating temperature range. This part is suitable for applications requiring higher precision and thermal stability.

Legacy Consideration:

ERJ-1TYJ752U (Panasonic) is electrically equivalent but marked "Not For New Designs." This part should be used only for legacy system maintenance or repair applications where design continuity is required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S1TF7501U replace ERJ-S1TJ752U in existing designs? A: Yes. ERJ-S1TF7501U is a direct functional replacement with improved tolerance (±1%) and temperature coefficient (±100ppm/°C). The tighter specifications make it suitable for any application accepting the original part.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging is supplied on continuous carrier tape for automated assembly equipment. Cut Tape is supplied in individual tape segments. Both formats contain identical components; selection depends on manufacturing equipment compatibility and order quantity requirements.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, meeting the same reliability and qualification standards as the ERJ-S1TJ752U.

Q: Can I use ERJ-1TYJ752U in new product designs? A: No. ERJ-1TYJ752U is marked "Not For New Designs" and should be reserved for legacy system support only. Use ERJ-S1TJ752U, ERJ-S1TF7501U, CRCW25127K50JNEG, or RMCF2512JT7K50 for new designs.

Q: What are the physical dimension differences between substitute parts? A: ERJ-S1TJ752U, ERJ-S1TF7501U, and ERJ-1TYJ752U measure 0.252" L × 0.126" W (6.40mm × 3.20mm). CRCW25127K50JNEG measures 0.248" L × 0.124" W (6.30mm × 3.15mm). RMCF2512JT7K50 measures 0.248" L × 0.126" W (6.30mm × 3.20mm). All parts have identical maximum seated height of 0.028" (0.70mm) and are mechanically compatible within 2512 package specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).
